IMPROVEMENT lN yBULLETIN-BOARDS.

Specification forming part of Letters Patent No. 177,202, dated May 9, 18.76 application filed March 30, 1876.

To all whom it may concern Be it know'nthat we, JESSE A. CRANDALL and DE .WITT O. TAYLOR, both of Brooklyn, Kings county, New York, have invented a new and Improved Bulletin-Board, of .which the following is a specification This invention has for its object to so construct a bulletinfboard that the removable letters placed thereon will b e locked secure, so they will not drop oft' when the board is "ibrated, and so also that the letters cannot be easily abstracted.

Our invention consists principally-.in providing such a bullctin-board with alongitudinal locking-bar, which extends over the upper edges ofa rowot' letters, and locks the same in position, as hereinafter more full y described.

In the accompanying drawing, Figure l represents a perspective view ot' a portionotl a bulletin-board containing our improvement. Fig. 2 is a vertical transverse section ot' amodilication ot' the same Figs. 3 and 4,- face views of further modifications, and Fig. 5 a vertical transverse section of Fig. 4..

Similar letters of reference indicate corresponding parts in all the figures."

A is a suitable bulletin-board, having one or` more horizontal ribs, a, for the support of the removable letters B B, to be displayed there'- on. (l is our im provedl locking bar. The same isv placed lengthwise against the face of the board A, directly over a row of letters, Bl B, to confine them in place, and preveuttheir unauthorized abstraction or spontaneous displacement. This bar C is interposed either as in Figs. 1, 2, and 3, between the upper edges of the letters and an upper rib, b, of the board A, orit may, as in Figs. 4 and 5,- be made in form of a clasp, to engage over the upper edge of the board, thus holding the letters in po`` sition. We prefer to use the locking-rod beneath the rib b, as it is in this form best adapted to boards displaying two or more horizontal rows of letters.

- The ribv b is, by preference, grooved on its under side, as shown, to properly secure the rodO, and the rod O may either partly lap over the letters, as in Figs. l and 3, or enter into grooves in said letters, as inFig. 2, or

merely rest upon them. When the rod is' withdrawn the letters can be removed, but not otherwise.

In Fig. l the board Ais, at one edge, shown to be provided with a pivoted rail, D, which, when swung against the end ofthe locking-rod O, will lock the same in place, and thus afford an additional security for the proper retention ofthe letters. But the rod may be confined by and removable locking-rod C, withthe device D for securing said rod C, substantially as herein shown and described.
